JEWELRY-STOCK.

SPECIFICATION forming part of Letters Patent No. 361,857, dated April 26, 1887.

Application filed December 8, 1886. Serial J`.\lo.220,9(i0. (Model.)

To all whom it may concern.-

f Be it known that I, SIDNEY O. BIGNEY, of Attleborough, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Jewelry- Stock, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to what is known as jewelry-stock or metallic structures77 made into various forms to be used by jewelers in constructing different articles of the trade.

The objects of my invention are to provide ornamental and neat jewelry-stock of a durable and novel character, andy which may bc formed from any of the sheet or plate materials well known in the art, and which may be made in a finished and trim state and be readily adaptable as a member or unit of various kinds of chains, pins, and jewelryin general.

My invention further consists in the peculiar and novel constructions and arrangements of the features of invent-ion, all as hereinafter fully described andclaim'ed.

In the accompanying drawings, illustrating my invention, Figure 1 represents a perspective View of a portion of a tube-like body forming the blank or material from which my improved jewelry-stock is formed. Figs. 2, 3, 4, 5, 6, and 11 represent, respectively, perspective views of different characters of members or units of my improved jewelry-stock.

Fig. 7 represents an edge view of a lace-pin constructed from a unit or piece of myjewelry-stock, as shown in Fig. 6. Figs. 8 and 9 represent perspective views of two different forms of chains constructed with chain-links composed of my improved stock. Fig. 10 represents a broadside view of another character of chain as made from my novel jewelrystock.

In the said drawings like numbers of reference designate corresponding parts throughout.

Referring to the drawings, in Fig. 1,13is a together, as at 14, so that the inner walls are brought iiatly together in contact, while the remaining portion of the sides of the tubular blank are formed into tube-like portions, as at 15. The walls of the tubular blank 13 are continuous or solid in contradistinction to being made in separate or unwelded unsoldered parts. Thus the tubular blank 18,0f cylindrical shape, is formed into the members or units 16, of several different characters. The j ewelrystock 16 is formed from the blank material by pressing the tube between cou ntersunk formerdies, each of which is provided with a semiconformation of the required tubular formthat is, if the tubular form required be cylindrical the semiconformations will each obviously be semi-cylindrical. In order to prevent the tubular portions from bei-ng compressed by the pressure of the dies, I employ a core or wire, which is placed within the cylindrical blank so as to lie inthe direction and position in which thc required tubular portion is to be formed. On bringing the dies together, the Y core or wire is disposed so as to take in the space made by the semi-conformations of the dies. In this manner the blank is readily formed with the contracted and tubular portions.l After the blank has been stamped into linished form, the core or wire is withdrawn from the same. The ornamental stock may be made from any of the sheet or plate metals, and the material may be ornamented in any manner, either by cutting through or perforating the body of the tube or indenting the edges thereof, or cutting into the surface of the sides thereof, as shown in Fig. 10. Such ornamenting may be made upon the blanks or on the stock after being formed up.

In Fig. 2 I have shown a unit or member of my novel jewelry-stock as having the axis of the tubular portion 15 concentric with the axis of the cylindrical tubular blank and the compressed portions 14 as extending alike to each side thereof in the same plane.

In Fig. 3 the tubular portion 15 is at one extreme side, while the flattened portion 14 is at the other side.

In Fig. 4 the tubularportions are disposed with their axes parallel at opposite sides thereof and with the compressed portion 14 intermediate thereof.

In Fig. 5 the tubular portion 15 is formed diagonally toY the compressed portions 14,

which are triangular in area, as clearly indicated.

In Fig. 6 the unit of stock 16 is made from a blank of more than twice the diameter of blanks 5 13 in Fig. 1, and is formed analogous tothe member 16 of Fig. 4. This piece of stock is suitable for a lace-pin or the like, and I have shown the same in Fig. 7 as provided with the pin 17 secured thereto in an ordinary manner.

In Fig. 8 I show the units 16 used as chainlinks and connected up with otherordinary forms of links, as 18, and furnishing a chain suitable for a watch-chain or neck-chain.

In Fig. 9 I have shown the chain-link members 16 as coupled together by the ordinary links 18, and this chain is suitable for a bracelet or fob chain.

In Fig. 10 I show still another manner of assembling the members 16 and their connecting-links 18.

In Fig. 11 the member 16 is formed analogous to that in Fig. 4, except that here the cross-section of the tubular portions 15 are polygonal instead of circular.

By the term tube I mean a hollow body of any shaped cross-section, and it will be readily understood that the tubular portions 15 of the stock-pieces maybe made of any cross-section.

Itis to be observed that the tubular portions 15 of the jewelry-stock 16 may be disposed across the member at any angle tothe directions here shown, thereby forming atnbular portion with closed ends instead of opened, as shown, and such a construction I deem equivalent to what I have shown, for 4obviously the same method must be used in forming the stock from the blanks. g

The band or tubular blank from which my stock is formed is compressed sidewise or at an angle to the axis of the body, in contradistinction to endwise or on the length of the axis. Of course the raised or tubular portions 15 of the stock-units may be disposed in any direction and may be placed as close together as possible, if desired, in order to produce a different effect.

. The jewelry-stock may be made from any of the metals used in the jewelry trade, and it will be seen that atubular blank may be made from the sheet and rolled-plate materials of any desired length and then formed up after my method, and in this condition may be sold and subsequently cut up into preferred lengths or units.

From the foregoing description it will be evident that by my method of making j ewelrystock a great variety of units and members of the same can be made, which will not require muchskill. The stock is well suited to all kinds of jewelry and may be put to other uses than what I show. For instance, some of the forms may be used readily as a leafin a hinge. The stock may be ornamented by cutting the surface or sawing through the material in the ordinary ways. The base metal of the -materials upon the interior of the blank is quite concealed in the finished state of the stock.

There may be various modifications made in the features of my invention without, how` ever, making a substantial departure from the essence thereof as herein described and claimed. f

I am aware that heretofore a bracelet stock or blank has been made in two separate parts which are united by upset edges into a blank having contracted portions not touching, and also tubular portions. I am further aware that an ornamental chain has heretofore been devised, which chain contains trefoil or quar-V terfoil tubing as units thereof. I therefore dishollow, substantially as and for the purposes set forth.

2. The herein-described jewelry-stock, constructed from material formed hollow or tubelike, with continuous walls, and having one or more portions thereof contractedand in contact and one or more portions thereofy formed hollow or tubular, substantially as and for the purposes set forth.

3. The herein-described ornamental jewelry-l stock, made from a tube-like body, formed with continuous walls, and having portions of the sides thereof formed compressed with the interior wallsin contact, and having portions ofthe sides thereof formed into hollow tube-like bodies, and the walls of the stock cut and ornamented, substantially as and for the purpose set forth.

4. The hereinbefore described method of making jewelry-stock, the same consisting in y inserting a core or wire in a tubular blank of any cross-section for limiting the compression of predetermined portions of the walls of the blank, then stamping or otherwise compressing the blank upon its transverse axis and forcing the walls of the blank together, except where the core or wire is disposed, and then, after stamping or forming the blank, removing the core or wire therefrom, thereby forming the jewelry--stockvhaving the external depressed and raised portions, substantially as herein set forth.

5. The h erein-described jewelry-stock 16,

IIO

formed from a tubular blank, 13, having continuous walls, and constructed with the contracted portions 14 touching, andthe tubular portions 15, substantially as and in the manner set forth.

In witness whereof I have hereunto set my hand.
